As water resources from the Ogallala Aquifer continue to decline, alternative sources of water resources should be considered to extend the life of irrigated agriculture in the Southern High Plains. The Dockum is a minor aquifer located beneath the Ogallala at depths of up to 2,000 feet. The Dockum Aquifer may be a suitable water source for irrigation supplementation; however, the cost to pump from the Dockum may not be economically profitable due to deep pumping depths, poor water quality, and low well yields. Results show that in some areas of the Dockum, it may complement irrigation water from the Ogallala for water thirsty crops.
